They’re removing the ability to download ebooks from Amazon. You are still able to add books via USB to your device.

The piracy is because you could download your Amazon ebook, strip the DRM and transform it to a more generic format, and distribute it. Unfortunately this now means you’ll be unable to make copies of your books for “backup in case Amazon decides to remove access” purposes.

There was a fuss a while back since the released source appeared to be waaaay out of date compared to what was being used.

They came out and said that they wanted the usernames feature to be developed fully before it got pushed public. Which they then did.
